  • 본 연구는 국내 농산물 유통에 있어 중추적인 역할을 하고 있는 농산물도매시장 중 전국에서 가장 큰 영향력을 가진 가락도매시장의 시장구조를 살펴보고자 하였다. 또한 가락도매시장의 주요 운영주체인 도매시장법인의 경영 효율성 분석을 통해 가락도매시장의 시장구조와 도매시장법인의 경영 효율성 간에 어떠한 관계가 있는지 분석해보고자 하였다. 분석 결과 2007년부터 2018년까지 가락도매시장 도매시장법인 간 경쟁수준은 상당히 낮은 것으로 나타났으며, 가락도매시장의 시장구조는 독점시장으로 분석되었다. 또한 가락도매시장 5개 도매시장법인의 평균 생산효율성은 0.95로 투입량 대비 산출량이 높은 효율적인 생산구조를 갖는 것으로 나타났다. 일반적으로 다양한 산업에서는 시장구조가 경쟁적일수록 기업의 생산효율성이 높아지는 구조이지만, 가락도매시장은 독점적인 시장구조임에도 불구하고 도매시장법인의 생산효율성이 높게 나타났다. 즉, 도매시장법인은 '수탁독점'이라는 혜택과 '지정제'라는 진입장벽, 위탁수수료 중심의 단순한 수익 창출 구조로 인해 일정수준 이상의 효율성을 담보할 수 있는 것으로 판단된다. 이와 같은 분석결과를 보았을 때 향후 농산물도매시장 활성화 및 생산자·소비자 권익 보호를 위해서는 통합정산체계와 새로운 유통주체의 도입 또는 기존 유통주체의 역할 유연화 등 농산물도매시장 유통주체 간 경쟁체계를 구축할 수 있는 정책추진이 필요하다고 판단된다.

  • Facility-based competition (FBC) in the telecommunications market is considered to have lower static efficiency in the short term and higher dynamic efficiency in the long term. Under service-based competition (SBC), the entrant can reduce its setup costs by leasing network facilities from the incumbent, which makes the entrant viable, pushes the market price down and promotes static efficiency. This paper attempts to measure static efficiency by comparing the profits of the incumbent and entrant in terms of consumer surplus and social welfare under each competition type by extending the Stackelberg model. The results, assuming a linear demand function and variation in regulatory level, show that FBC results in higher social welfare than SBC on the whole. However, SBC accompanied by strong regulation is also shown to have the potential to be superior over FBC. It is also revealed that FBC exhibits a higher producer surplus (particularly, the incumbent's producer surplus) and is, therefore, more desirable in terms of dynamic efficiency. When the entrant's cost is high in FBC, social welfare is shown to be lowered, implying that cost competitiveness is a necessary condition for social welfare.

  • Purpose - This paper analyzes the market efficiency focusing on the long memory properties of the domestic futures market. By decomposing futures prices into yield and volatility and looking at the long memory properties of the time series, this study aims to understand the futures market pricing and change behavior and risks, specifically and in detail. Design/methodology/approach - This study analyzes KOSPI 200 futures, KOSDAQ 150 futures, 3 and 10-year government bond futures, US dollar futures, yen futures, and euro futures, which are among the most actively traded on the Korea Exchange. To analyze the long memory and market efficiency, we used the Variance Ratio, Rescaled-Range(R/S), Geweke and Porter-Hudak(GPH) tests as semi- parametric methods, and ARFIMA-FIGARCH model as the parametric method. Findings - It was found that all seven futures supported the efficiency market hypothesis because the property of long memory turned out not to exist in their yield curves. On the other hand, in futures volatility, all 7 futures showed long memory properties in the analysis, which means that if new information is generated in the domestic futures market and the market volatility once expanded due to the impact, it does not decrease or shrink for a long period of time, but continues to affect the volatility. Research implications or Originality - The results of this paper suggest that it can be useful information for predicting changes and risks of volatility in the domestic futures market. In particular, it was found that the long memory properties would be further strengthened in the currency futures and bond rate futures markets after the global financial crisis if the regime changes of the domestic financial market are taken into account in the analysis.

  • 본 연구는 예상환율변화율, 예상인플레이션 차이, 및 이자율 차이를 활용하여 한국의 외환시장, 실물시장, 및 화폐시장 간의 상호관계를 분석하였으며, 계량경제기법으로는 합리적 기대가설과 GARCH-M 모형을 적용하였다. 또한, 국제 Fisher 효과를 분석하여 국내외의 실질이자율이 국가간 자본유출입에 미치는 영향도 분석하였다. 분석결과에 의하면 한국의 경우 외환시장의 효율성을 실물시장 및 화폐시장간의 유기적인 관계로 이해하기에는 한계가 있지만 외환시장에서 결정되는 환율은 국가간 실질이자율의 충격에 영향을 받는 것으로 판명되었다. 따라서 외환시장의 안정성을 확보하기 위해서는 국가간 실질이자율의 차이를 안정적으로 유지하는 정책을 수행하여야 할 것이다.

  • The purpose of this paper is to examine the relationship between regional financial development and corporate investment efficiency as well as the relationship between firm-level characteristics and corporate investment efficiency. Using a large sample of A-listed companies in China from CSMAR database between 2003 and 2016, this paper explores corporate investment efficiency and its influencing factors in emerging market on the basis of heterogeneous stochastic frontier model. The results show that: (1) the average investment efficiency of Chinese listed companies is 74.5%, and the investment efficiency of large enterprises, state-owned enterprises and enterprises with relatively high financial development level is significantly higher; (2) compared with average corporate investment efficiency in the year 2003, the investment efficiency of different types of enterprises in 2016 is significantly higher, and the gap is gradually widening; (3) enterprise heterogeneity namely firm size, nature of property right, and institutional environment reflected by the level of regional financial development indirectly affects corporate investment efficiency by influencing the financing constraints and uncertainty. The findings suggest that to improve corporate investment efficiency in emerging market, financial market should be accelerated, regional balance should be restored and the differences among regions, industries and differences between public and private sectors should be eliminated.

  • Home Meal Replacement (HMR) products are ready-to-eat or pre-cooked food products that are consumed at daily home. HMR market has grown rapidly due to societal changes: increases in female social activities, silver population, and one-person households. Consumption channels of HMR can be classified into take-out, delivery, and retail. In Korean HMR market, retail sector is largely growing, but companies are focusing their business on the home delivery sector. Moreover, franchise companies are expanding their areal coverage in the HMR market based on their multi-unit strategy. However, more research on the HMR market is needed as existing studies are limited in conceptualization, classification, and processed food from malls or home-shopping channels. Therefore, we conducted the efficiency analysis on Gukseonsaeng, one of franchises that applied the take-out channel, using DEA method. According to the research on 29 franchisees of Gukseonsaeng, 77.9% of input appeared inefficient for technical efficiency, while 53.3% of input appeared inefficient for scale efficiency. Thus, we found that franchises of Gukseonsaeng are structured in increasing returns to scale (IRS), so enhancing efficiency by expanding scales need to be implemented.

  • Intermediaries are presenting not only transactional information that orchestrates electronic transaction, but also market related information and knowledge useful for sellers' understanding of the market status. However, we do not have strong evidence that the market related information and knowledge is properly utilized by sellers and that it has an actual influence on sellers' performance. According to the research result, absorptive capacity and the pattern of information system utilization is statistically significant to sellers' performance mediated by operational efficiency and market knowledge creation. Especially, explorative utilization of information system and realized absorptive capacity has a stronger influence on sellers' performance mediated by market knowledge creation. With this research result, this study maintains that sellers are required to absorb and utilize market related information and knowledge more actively through explorative utilization of information system to achieve better performance in the e-marketplace. On the other hand, intermediaries are recommended to provide abundant and valuable market related information and knowledge for the sellers to build up better e-marketplaces.

  • The purpose of this study is to ascertain that how the futures market of the Japanese frozen shrimp that is the only fisheries asset all over the world can be efficient. Accordingly, this paper examines efficiency and information flow of the Japanese frozen shrimp market using data from Kansai Commodities Exchange frozen shrimp futures closing prices and spot prices. And then this paper estimates a forward price model using that data. From the model, risk premium is estimated and we could also analyse the future information flow into the futures market which reveals future spot prices. This thesis reached to conclusions as follows: First, the null of zero risk premium is rejected and the value of that is negative. Second, the time pattern of information flow into the futures market is that most of the information on future price arrives within a week and for the last week, most of relevant information is already incorporated. The result of this study contrasts with that of Stockman(1978) about currency futures market of U.S.
